This invention consists in the improved construction and combination of parts to be more fully described hereinafter Jand the novelty o-f which will be particularly lpointed out and distinctly claimed.

In the accompanying drawings to be taken as a part of this specification there is 'fully and clearly illustrated a preferred vembodiment of the invention, in which dra-wings:

Figure 1 is a `View in front lelevation of a register embodying the invention and positioned in a room wall with the floor in sectionand shou ing a portion of the furnace Acasing, Y

Fig. 2 is a view'in section on the line -II-II of Fig. 1,

Fig. 3 is a View in section on the line III-III of Fig. 2,

- Fig. 4 is a View in-section on the line IV-IV of Fig. 2, and Y Fig. 5 is a detailed plan view showing -a portion of an air flow controlling Adamper and its lever operating mechanism.

Referring to the drawings by characters of reference, l and 2 designate adjoining-rooms-or spaces having a floor 3 and separated by a vertical room wall or partition t. Centrally below the wall t the door 3 'has arectangular opening therethrough in which is positioned a floor-type air-heating furnace of any yof the usual constructions having a rectangular outer casing 5 jw'ith a surrounding outturned flange it-which rests upon the peripheral portion of the floor surrounding the mentioned opening.` Within the casing 5 there is a combustion chamber Il and radiators 8 which are spaced from the casing 5 .by a rectangular surrounding partition havingran inwardly converging .continuous upper edge portion -I 0.

The register which :seatsonthe rurnaccis 2 positioned in a rectangular opening through `the wall 4 and has an inner casing Il, an Aouter lcasing 12, `and a pair of grille 'supporting members i3 and I4 `which 'house the opposite sides or" the register.

The inner casing H has spaced vertical end Walls I5, It with upward converging side edges. The end walls are joined by upper and lower top wall members H, t8, respectively, having down-turned iianges spot wel-ded ror otherwise securedto the end walls. The-upper and lower wall vmez-nbers H, I8rare vertically "spaced Aand inclined upwardly from their mid-portions toward the side edges of the -end wall zmein-bers 25, VI-'S to provide -opposi-tely fdischargingair passageways extending from :end-to end of the inner casing. The lower side edge portions of the end walls 15,- it are recessed and joined-Ilby side wall members 119, 2t `which seat-in the recessed l-portions -and have end iianges 2i which overlap the en-d walls 115,' fl-S and lare spot vwelded or otherwise Asecured thereto. The side wail members I-9, 2t terminate at their upper horizontal edges in out-turned flanges which terminate in the respective planes of the side edges-oi the end walls v-ii-li, i6 above therecessed portions. The top edge flanges ofthe side wall members i9, 2t,- the end walls 1.5, -I-B and vthe lower top wall member Y`|28 `deiine -oppositel-ydirected nwarm air discharge outlets 22, 23 from the inner casing l-I.` The side wall `members It, 2t eac-h has a horizontal outward 'extendingV bottom portion y2t whichy overl-iesffthe end portions of the lspace within the fur-nace partition it. The lower edge portions of the 'end walls 15,' it terminate in downward and out-ward inclined flanges which seat on-the furnace partitioniiange it and form a Vcontinu-ation of similar iianges entend-ing downward :from the -sidewail bottom portions 24, whichV last-*named 'r'ia-nges also seat on the furnace' A`flange portion It. Through the end wail-ls 15,- IG at points located between the upper and lower top walls-i7, t8 there isa plurality of air inflow apertures-25 leading-to the passageways between these mem-bers.

. Air Aflow to the outlets' 22,- 23 may be selectively controlled Iby `a `plate type damper 2t which is pivoted on sa shaft 2-1 extending horizontally between and through supporting apertures in the end lwalls yI-5,-lt`. The damper 26 has a spring pressed friction pin 2t which bears against the inside face of the `end wal-l 'E15 `to iri-ctional-ly hold the -damper v26 in adjusted position. :EX- tending ytransverse to the -plane orY the dam-per and vsecured tthereto -and--apertured for 'passage aesaees 'i 1 of the shaft 21 therethrough there is an arm 29 extending equally from opposite sides of the damper. Extending downward from each end of the arm 29 there is a pivoted link 39. These links 39 are pivoted at their lower ends respectively to oppositely directed damper operating levers 3l, 32 which are pivoted respectively intermediate their ends on pivot pins 33, 34 which are fixed in and to the end wall I5. The upper edge portion of the damper 26 extends above the shaft 21 and swings within a concave or upwardly curved recess portion 35 in the lower top wall I8. The portion 35 also provides clearance space for the damper arm 29 and links 3G, as indicated in dash lines, upon swinging of the damper. Clearance for the opposite end portions of the shaft 21 and reinforcing for the end walls I5, I6 is provided by vertical plate members 33 secured one to the outer face of each of the end walls I5, II and each of which has a Vertical reinforcing angle member 31 abutting its respective end wall.

The outer casing I2 has vertical end walls 38, 39 which are spaced from the end walls I5, I6, respectively, and which are joined by a top wall 49 which is spaced above the upper top wall I1. lThe top wall 49 is reinforced by a channel member 4I which also extends between the end walls 33, 39 and has side iianges by which it is secured to the top wall 49, as by spot welding. The channel v member 4I also serves to form with the top wall 40 and the end walls 38, 39 a dead air space underlying the horizontal portion of the wall 4 which overlies the register receiving opening. The lower edges of the end walls 38, 39 seat upon the furnace casing flange 6. The inner casing I I is positioned endwise Within the outer casing I2 by vertical partition members 42, which extend inward toward each other from the vertical center lines or mid-portions of the outer casing end walls 3B, 39, the partition members 42 each having a flange 43 lying against its respective end Wall and secured thereto by spot welding or the like. The partition members 42 each has its free inner edge portion recessed as at 44 to provide clearance for the ends of the shaft 21 and the inner casing end wall reinforcing members 35. The partition members 42 are joined above the inner casing top wall I1 by an angle member 45 having a horizontal flange spot welded or the like to the channel member 4I and having a vertical flange extending downward toward the top wall I1, this vertical flange and the partition members 42 cooperating to substantially block or materially reduce air flow from one side to the other of the outer casing around the inner casing. The grille supporting members I3, I4 which house the opposite sides of the register each has opposite end face portions 4B with vertical inner edges which seat against the opposite faces of the wall 4 at the sides of the register receiving opening therethrough. Each pair of end face portions 46 is joined by a top face portion 41 and a side face portion 48 which surrounds its grille receiving opening. Positioned in each of these grille receiving openings there is a grille member 49 having vertical or upright slot-like apertures therethrough. The grille member receiving openings extend laterally beyond the end Walls I5, I6 of the inner casing member and to the end walls 38, 39 of the outer casing member so that these openings overlie or extend across the Warm air discharge outlets 22, 23, registering therewith, and overlap the inlets to the passageways 50, 5l on opposite sides of the partition member 42 between the end walls I5 and 38 and also overlap the inlets to the passageways 52, 53 on opposite sides of the partition member 42 between the end walls I6 and 33. The grille members 49 have end groups of apertures or slots 54 through which return air from the rooms can flow to the passage- Ways 59, 5I, 52 and 53. Each of the grille members 49 also has a central group of slots or apertures 55 overlying the warm air outlets 22 and 23 for discharge of the warm air therethrough into the rooms on opposite sides of the wall 4. Each of the grille receiving members has vertical flanges 56, 51 extending one from each side edge of the grille receiving opening. The flanges 56, 51 overlap and laterally engage the outside faces of the side edge portions of the end walls 38, 39, respectively. The flanges 53, 51 are adjustably secured for horizontal movement to the end walls 38, 39 by bolts 58 passed through apertures in the flanges 56, 51 and slidable laterally in horizontal slots 59 in the end Walls 33, 39.- The bottom edges of the side face portions 43 are preferably recessed between their ends as at 59 (see Fig. 4) to provide receiving spaces for the horizontal floor grids or grilles 5I which seat at their three outer edges 0n the floor 3 in overlying relation to the return air downflow space between the furnace casing 5 and partition 9. The grilles 6I also overlie the inner casing bottom portions 24 and have their inner edges extending substantially to the inner casing side walls I9, 20, respectively. The damper levers 3|, 32 project through the apertures 55 for manipulation of the damper 26 from the exterior of the register.

The operation of this register is as follows: The damper 26 may be positionedV as shown in full line in Fig. 2, which will cause the air heated by the furnace to discharge substantially equally from the inner casing outlets 22, 23. By pushing downward upon the operating levers 3l, 32, the damper 2B will be moved at its lower portion toward that side of the register which has its operating lever depressed. Full depression of either damper lever will move the damper for substantially full cut-off of air flow through that side of the register on which the damper lever was manipulated. When the furnace is operating and heating air, the heated air rising within the furnace partition 9 will rise into the inner casing, a portion being deflected thereinto by the horizontal bottom portions 24 and will discharge through the open passageways 22, 23 and their respective grille apertures 55 into the rooms-to be heated. The upow of air within the partition 3 will draw air downward through the grilles SI into the passageway surrounding the partition 3, beneath the lower edge of this partition 9, as is well known in the art, and thence upward as above described around the combustion chamber 1 and radiators 8 to the interior of the inner casing II. Some of the return air will be drawn through the grille openings or slots 54 into the passageways 53, 5I, 52 and 53 and thence flow downward with the air entering the grilles 3| to be heated as above described. The air flowing downward through the passageways 50, 5I, 52 and 53 provides a layer of cooling air interposed between the heated air in the inner casing II and the portions of the Wall 4 at the sides of the register receiving opening. The lower top wall I8 of the inner casing will be heated in part by direct radiation from the combustion chamber 1 and radiators 3 and in part by the heated current of air, and therefore the air in the passageways between the upper and lower top. walls I1,

webwml;

it' will Lbe heated and .now Aoutvvardrom these passageways, discharging into the rooms :through the upper portions of the grille slots or apertures 55. The air discharging from these passageways will cause relatively cool air from the rooms entering the grille slots 5t to iiow throughthe end wall apertures 25 into the passageways between the upper and lower top wall members I1, I8 to cool these walls and particularly the Wall I8, the air entering through the apertures 25 discharging .as above described into the rooms through the grille slots 55.
